A simple grammar test (elementary/ pre-intermediate levels) that could also be used as a worksheet for grammar revision. Again it's fully editable so you can easily adjust it to your needs. In ex.1. students have fill in the blanks with CAN or CAN'T, in ex.2. they have to write the correct form of HAVE GOT/ HAS GOT. In ex.3. students have to give short (+) positive /(-)negative answers to the questions and in ex.4. they have to make the given mixed sentences positive (+), negative (-) and interrogative (?) by using CAN or HAVE GOT / HAS GOT. Hope it's useful. Have a great morning/day/evening!
